The Zeiss Batis Distagon T* 2/25mm is a full-frame (FE) wide-angle prime lens for the Sony E-mount, announced by Zeiss on April 22, 2015.
Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 37.5mm.
The lens features a weather resistant aluminum barrel construction with a matte black finish and a rubber focus ring.
Along with the Zeiss Batis Sonnar T* 85mm F1.8, the Batis Distagon 25mm was one of the first two lenses in which the traditional distance scale on the lens is replaced with an OLED display.
[1] The OLED display is integrated into the top of the lens barrel, and highlights the focus distance and depth of field range of the lens,[1] which can be set to display at all times, never, or only when focusing manually.
